20L Liquid Nitrogen Tank with 6 Canisters – Cryogenic Dewar

The 20L Liquid Nitrogen Tank with Canisters is a vacuum-insulated cryogenic storage vessel designed for the safe storage and preservation of liquid nitrogen and temperature-sensitive biological samples. It is commonly used in laboratories, hospitals, fertility centres, research facilities, veterinary applications and artificial insemination programmes. The tank typically features a high-strength aluminium alloy body, narrow neck design, vacuum insulation and removable stainless-steel canisters for organizing and retrieving stored samples. A common 20L configuration uses a 50 mm neck opening and 6 canisters, providing a balance between long liquid nitrogen holding time and convenient sample access. Because exact dimensions and holding time vary by manufacturer and neck size, the specifications below reflect a common 20L / 50 mm / 6-canister configuration suitable for marketplace listing.
